[u-u] Linux machine[s ] for an online course

[arocker at Vex.Net]

Next week I will need at least at least one Linux machine, available
remotely for an administration course. (With the obvious need to fiddle as
root.) The cheaper the better. Also, the fewer unknowns, the better.

There's a VM available to go with the course, but it needs a host machine.
I'm wondering if AWS or Azure might have something I could use.

Any suggestions, anyone?
